BORING AND TURNING MILL.

SPECiFICATION forming part of Letters latent No. 684,944, dated October 22, 1901.

Application filed July 1, 1901.

ToctZZ whom it may concern:

Be it known that I, GEORGE WILLIAM MORE- TON, a citizen of the United States, residing at Wilmington, in the county of Newcastle and State of Delaware, have invented certain new and useful Improvements in Boring and Turning Mills 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, ,such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to boring and turning mills; and it consists in the'novel con struction and combination of the parts, hereinafter fully described and claimed, whereby the cutting-tool is adjusted.

In the drawings, Figure 1 is a front view of a boring and turning mill provided with an attachment according to this invention. Fig. 2 is a sectional plan View of the attachment drawn to a larger scale. Fig. 3 is a detail view. Fig. 4 is a cross-section through the cross-rail and one of its saddles.

, A is the cross-rail of a boring and turning mill, which is slidable vertically on uprights B, supported on a bed 0.

.D represents saddles which are slidable horizontally on the cross-rail A, and E represents tool-bars which are slidable crosswise of the saddles and which carry the cutting-tools.

F is the cross-rail rod, which is operatively connected with the tool-bars E, and G is the cross-rail screw, which is operatively connected with the saddles D. The rod F and screw G are provided with handles f. and g at their ends or with other approved means for revolving them. The cross-rail rod F has a worm 0 splined on it, which gears into a wormwheel 0, secured on the shaft 0, which is journaled in the bearing q, supported by the sad dle. A toothed pinion p on the shaft 0 gears into a toothed rack on the tool-bar E and operates to raiseand lower it. The cross-rail screw G engages with a nut s, which is carried by the saddle.

All the fibOV6-'-1Il6l1l3l01l8(l parts are of approved construction, such as shown in the patents issued in my name, No. 569,344, dated October 13, 1896, and No. 612,783, dated October 18, 1898.

In all such large machines two persons are Serial No 66,688. on model.)

required to adjust the cutting-tools when the work is comparatively small, because of the distance of the cutting-tools from the handles f and g, one person being required to watch the cutting-tools and the other to manipulate the said handles. g

In order that the cutting-tools may be adjusted by one person, each saddle D has a bracket cl, which is preferably bolted to it by screws d, so as to be easily removable. A beveled toothed wheel 6 is splined to the crossrail screw G and is provided with a hub e, which is journaled in the bracket d. A beveled toothed wheel his secured on a shaft h, which is also journaled in the bracket d and is provided with means for revolving it, such as a handlej. The wheel h gears into the wheel 6, so that the screw G can be revolved by turning the handle j. A beveled toothed wheel is is splined in'a similar manner to the cross-rail rod F and is also journaled in the bracket cl. A beveled toothed wheel m is secured on a shaft m and is provided with means for revolving it similar to the shaft h. The wheel m gears into the wheel 70. The beveled toothed wheels and their operatinghandles move with the saddle along the crossrail and are always in convenient proximity to the tool. 1 v

' What I claim is- 1. The combination, with a cross-rail, asaddle slidable thereon, an operating-shaft journaled longitudinally in the cross-rail, a worm splined on the said shaft, a tool-bar carried by the saddle, and intermediate driving mechanism connecting the said Worm with the said toolbar; of a bracket secured to the said saddle, a toothed wheel splined, on the said operating-shaft and having its hub j ournaled in the said bracket, a shaft j ournaled in the said bracket and provided'with means for revolv ing it,- and a toothed wheel secured on the last said shaft and gearing into the aforesaid toothed wheel, substantially as set forth.

2. The combination,with a cross-rail, a saddle slidable thereon, an operating-screw journaled longitudinally in the cross-rail, and a nut carried by the saddle and engaging with the said screw; of a bracket secured to the said saddle, a toothed wheel splined on the said operating-screw and having its hub j ournaled in the said bracket, a shaft journaled in the said bracket and provided with means for revolving it, and a toothed wheel secured on the last said shaft and gearing into the aforesaid toothed wheel, substantially as set forth.

3. The combination, with across-rail, a sad dle slidable thereon, a tool-bar slidable crosswise of the saddle, and a cross-rail screw and a cross-rail rod operatively connected with the said saddle and tool-bar respectively; of a bracket secured at one end of the said sadd1e,toothed driving-wheels havinghubs which
